Comparative leaf and peduncle anatomy of four Turkish endemic Onobrychis Mill. taxa

Abstract

In this study, leaf and peduncle anatomy of four Turkish endemic taxa of the genus Onobrychis from sect. Onobrychis, including Onobrychis quadrijuga, sect. Heliobrychis including Onobrychis argyrea subsp. argyrea, and sect. Hymenobrychis including Onobrychis tournefortii, and Onobrychis albiflora were investigated for the first time. Numerous quantitative and qualitative characters in the leaf and peduncle cross sections were determined and studied. Results showed that, for the leaves quantitative characteristics and for the peduncle qualitative characteristics are more distinctive between examined taxa. As the main, while in the leaf, mesophyll thickness, stomata and epidermis cells features, in the peduncle, especially, the contour of the peduncle and location of cavities in cross section, and density of papillae on hair surface were represented considerably variation between examined taxa

Türkiye endemiği olan dört Onobrychis Mill. taksonunun karşılaştırmalı yaprak ve pedünkül anatomisi

Abstract

Bu çalışmada, Türkiye’de yayılış gösteren Onobrychis cinsine dâhil olan, sect. Onobrychis’e ait O. quadrijuga, sect. Heliobrychis’e ait O. argyrea subsp. argyrea, sect. Hymenobrychis’e ait O. tournefortii ve O. albiflora taksonlarının yaprak ve pedünkül anatomisi ilk defa incelenmiştir. Yaprak ve pedünkül enine kesitleri üzerinden birçok nitel kalitatif ve nicel kantitatif karakterler tespit edilerek çalışılmıştır. Sonuçlara göre yapraklar için nicel, pedünkül için ise nitel karakterler, taksonlar arasındaki ayırt edici özellikler açısından önemlidir. Temel olarak, yapraktaki mezofil tabakası kalınlığı, stoma ve epidermis hücrelerinin özellikleri, pedünkülde ise özellikle enine kesit şekli, tüy yüzeyindeki papilla yoğunluğu, boşlukların konumları gibi özellikler incelenen taksonlar arasında dikkate değer şekilde varyasyon göstermektedir
